How to make minecraft not laggy on windows 8?

It's super laggy and I need a way that won't make it laggy for SURE because it'super annoying and I can't even like play it when it's like this.

Reboot

Maybe you have a computer in which the specifications don't meet the requirements to play the game. I can't tell you to make it less laggy based on the information given to me.

You are so lucky to get Minecraft to boot up with W8 let alone run slow, Windows 8 is locked down to only install and run Windows 8 software that has the M$ secure boot digital signature with the software, Minecraft don't have that signature. Because it's a Linux game that's been ported to windows, Xp and 7. Not W8
You being a W8 user are NOT allowed to download and install what you want, Everything for W8 has to be bought from M$ W8. No doubt you will find this out sooner or later, when you do you will want to Jail Break windows 8, so that you can install what you want when you want. Windows is not the only computer operating system in the world
